The mini-campaign follows US army veteran Gerald Wilkins as he fights to stop the Sun Gun, which the trailer above bills as the “deadliest weapon ever made.” Presumably, he will succeed in some deeds along the way. The adventure takes place in Nazi-controlled Alaska, and Wilkins is equipped with a stolen battlewalker you may recognize as the stilts from the base game.

As always, the content requires you to have reached chapter two of the main story, and will be accessible either through the SAS machine on the submarine or via the main menu.

The Deeds of Captain Wilkins is available in standalone form for $9.99 / £7.99 / €9.99, or as part of the season pass – which currently happens to be on sale for $14.99 / £10.79 / €14.99.

All of Wolfenstein II is currently on sale through Steam, in fact. The base game is $29.99 / £19.99 / €29.99, and the Digital Deluxe Edition which includes the season pass is $39.99 / £27.49 / €39.99. All the special promotions last until March 19.
